Waterproof connector

The present invention relates to a waterproof connector, and more particularly to a waterproof connector in which one or more contacts are integrally formed with a casing made of an insulating resin.

In recent years, electronic devices such as computers and mobile phones have been widely used, but such electronic devices usually have connectors for connecting signals to external devices for signal transmission. In electronic devices, the demand for waterproof functions has increased, and along with this, waterproof connectors having waterproofness have been developed.

Further, in order to prevent the transmitted electrical signal from being affected by electromagnetic waves from the outside, a connector capable of shielding electromagnetic waves is expected.

A connector having both water repellency and electromagnetic wave shielding as described above is disclosed, for example, in Patent Document 1. As shown in Fig. 13, the connector has a side connector housing portion 2 in which a housing-side connector is housed in a cylindrical metal case 1, and a conductive connection is disposed in the opposite-side connector housing portion 2. The contact 3 is used, and the outer casing 1 and the contact 3 are integrated by insert molding or the like. The structure formed by casting in the casing 4 formed of the insulating resin.

One end of the contact 3 is exposed in the opposite side connector housing portion 2 to form a contact portion 3A in contact with the contact of the opposite side connector, and the other end of the contact 3 is exposed on the back of the housing 4 to be connected to the substrate. The board connecting portion 3B embeds the fixing portion 3C disposed between the contact portion 3A and the board connecting portion 3B in the casing 4 to fix the contact 3 to the casing 4.

The contact 3 is integrally molded into the casing 4, so that the surface of the fixing portion 3C of the contact 3 is followed by the insulating resin forming the casing 4, preventing water from passing through the casing 4 and the contact 3 from the outside of the connector. The boundary portion is immersed in the back of the casing 4, that is, on the side of the substrate on which the connector is mounted.

However, when the electronic device to which the connector is mounted is immersed in the water so that the water is immersed in the opposite side connector accommodating portion 2 of the connector, the water pressure P acts on the housing 4 forming the bottom portion 5 in the fitting direction of the opposite side connector accommodating portion 2. By the water pressure P, the shearing force in the fitting direction is generated between the fixing portion 3C of the contact 3 and the casing 4. Therefore, the insulating resin forming the casing 4 is peeled off from the surface of the fixing portion 3C of the contact 3, which may impair the waterproofness of the connector.

The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a waterproof connector that maintains water repellency even when subjected to water pressure in the opposite side connector housing portion.

Embodiment 1

Fig. 1 is a view showing the configuration of a waterproof connector according to a first embodiment of the present invention. The waterproof connector has a casing 10 having an outer shape of a substantially rectangular parallelepiped shape, a plurality of contacts 20 fixed to the casing 10, and a casing 30 fixed to the casing 10 and shielding a plurality of contacts 20. The casing 10 is formed of an insulating resin, and the contacts 20 and the casing 30 are formed of a conductive metal material.

The casing 10 has a concave opposite-side connector accommodating portion S that opens on the front surface 10A side of the casing 10 along a fitting shaft C of an opposite-side connector (not shown), and the casing 30 has a configuration on the opposite side. A hollow fitting portion 31 that fits into the opposite side connector in the housing accommodating portion S. The outer casing 30 further has a pair of outer casing side substrate connecting portions 32 that are exposed to the outside of the casing 10.

Further, the plurality of contacts 20 are arranged in a direction orthogonal to the fitting axis C, and the contact portions 21 disposed at the tips of the respective contacts 20 are disposed in the fitting portion 31 of the casing 30. On the other hand, as shown in FIG. 2, the contact side substrate connecting portion 22 disposed at the rear end of each contact 20 is exposed from the rear surface 10B of the casing 10 to the outside of the casing 10.

Here, for the sake of convenience, a direction extending in parallel from the front surface 10A of the casing 10 toward the rear surface 10B and the fitting axis C is referred to as an X direction, and an arrangement direction of the plurality of contacts 20 is referred to as a Y direction, and an X direction and Y The direction in which the direction is perpendicular is referred to as the Z direction.

As shown in FIGS. 3 and 4, the casing 10 has a bottom portion 10C in the direction of the fitting axis C of the opposite-side connector accommodating portion S, and has an X-direction from the bottom portion 10C toward the fitting axis C. 10A extended tongue 10D.

Each of the contacts 20 is formed of a rod-shaped member or a flat member, and the contact portion 21 protrudes from the bottom portion 10C in the fitting direction of the opposite-side connector housing portion S of the housing 10 toward the -X direction. In the portion S, the surface 21A in the -Z direction toward the contact portion 21 is held in contact with the tongue portion 10D of the casing 10, and the surface 21B in the +Z direction opposite to the surface 21A is connected to the opposite side. The device housing portion S is open. Further, the contact 20 has a contact-side fixing portion 23 that is buried in the casing 10 and that fixes the contact 20 to the casing 10 between the contact portion 21 and the contact-side substrate connecting portion 22.

On the outer peripheral surface of the contact-side fixing portion 23, a contact-side waterproof shape portion for water immersion which is formed by cutting a plurality of grooves or projections which are parallel to each other and which is formed along the boundary surface between the contact-side fixing portion 23 and the casing 10 is formed. twenty four.

Further, the outer casing 30 has a connection between the connection fitting portion 31 and the pair of outer casing side substrate connecting portions 32, and is embedded in the casing 10 to fix the outer casing 30 to the outer casing side fixing portion 33 of the casing 10. The outer casing side fixing portion 33 extends from the +X direction end portion of the -Z direction side portion of the hollow fitting portion 31 in the +X direction in the casing 10, and is connected to the pair of outer casing side substrates through the casing 10 The joints 32 are connected.

The contact side fixing portion 23 and the outer casing side fixing portion 33 are embedded in the casing 10 when the plurality of contacts 20 and the outer casing 30 are cast and molded into the casing 10.

Further, in the bottom portion 10C of the casing 10, a contact adhesion force generating recess 40 is formed in the vicinity of the root portion of the contact portion 21 of each contact 20 and in the vicinity of the surface 21B in the +Z direction. The contact adhesion force generating recess 40 has a shape recessed from the surface of the bottom portion 10C of the casing 10 along the fitting axis C opposed to the rear surface 10B of the casing 10, and communicates with the opposite side connector housing portion S.

The contact-receiving force generating recess 40 uses the water pressure acting on the inner wall surface of the recess 40 by the contact force to cause the housing 10 in contact with the contact-side fixing portion 23 when the electronic device in which the connector is mounted is immersed in water. The portion 10E faces the contact side fixing portion 23 and is followed.

As shown in Fig. 5, a plurality of contacts 20 are provided with a plurality of contacts and a force generating recess 40.

The waterproof connector according to the first embodiment is mounted on a substrate mounted in a casing of an electronic device such as a mobile information terminal, and exposes the opposite connector housing portion S to the outside of the casing of the electronic device. The periphery of the 10 is protected from the inside of the casing of the electronic device by a waterproof mechanism (not shown). However, when the electronic device is dropped into the water or the like, the water is immersed in the connector accommodating portion S attached to the waterproof connector of the electronic device. The contact is also immersed in the contact with the opposite side connector accommodating portion S, and the force is generated to form the recess 40. As shown in Fig. 6, the water pressure P acts on the contact and the force is concave. The inner wall surface of the portion 40. The water pressure P acts on the entire inner wall surface perpendicularly across the inner wall surface of the contact-producing force generating recess 40, but the housing 10 formed of the insulating resin has a certain degree of elastic force in addition to the potential rigidity, and The casing 10 is supported by a substrate or a casing of an electronic device (not shown). Therefore, in the portion 10E of the casing 10 that is in contact with the contact-side fixing portion 23, an adhesion force due to the water pressure P toward the contact-side fixing portion 23 occurs. Therefore, it is possible to effectively prevent water from entering the +X direction along the boundary surface of the contact side fixing portion 23 on the +Z direction side and the boundary surface of the casing 10. Further, the water pressure P acting in the +Z direction, which is a direction away from the contact-side fixing portion 23, is blocked by the substrate or the casing of the electronic device (not shown) that supports the casing 10.

Assuming that the bottom portion 10C of the casing 10 does not have a contact and a force generating recess 40, the water pressure P generates only a shearing force in the fitting direction between the contact side fixing portion 23 and the casing 10, but by the contact force The formation of the concave portion 40 is formed by the water pressure P, so that the portion 10E of the casing 10 that is in contact with the contact-side fixing portion 23 faces the contact-side fixing portion 23, and the casing 10 from the contact-side fixing portion 23 is prevented. Peeling improves water resistance.

Since the plurality of contacts 20 are disposed at the bottom portion 10C of the casing 10 with a plurality of contacts and the force generating recesses 40, the recesses 40 are generated by the respective contacts and the portions 10E of the casing 10 are followed by corresponding touches. The contact side fixing portion 23 of the point 20.

Further, as described above, the contact-side waterproof shape portion 24 is formed on the outer peripheral surface of the contact-side fixing portion 23 of each of the contacts 20, and the combined contact force generates a waterproof effect by the presence of the concave portion 40, thereby effectively preventing water from being relatively opposed. The side connector housing portion S is immersed in the boundary portion between the housing 10 and the contact 20 It is to the rear surface 10B side of the casing 10, that is, the substrate side on which the waterproof connector is mounted.

The opposite side connector is inserted into the opposite side connector accommodating portion S of the waterproof connector along the fitting axis C, and when fitted to the fitting portion 31 of the outer casing 30, a plurality of contacts with the opposite side connector are arranged. The contact portions 21 of the plurality of contacts 20 in the opposite side connector housing portion S are in contact with each other to electrically connect the opposite side connector and the waterproof connector.

Further, at the time of fitting with the opposite-side connector, each of the contact-contacting force generating recesses 40 is not blocked by the opposing-side connector, and can be in a state of being in communication with the opposing-side connector accommodating portion S.

Embodiment 2

The contact-contact force generating concave portion 40 used in the first embodiment has a curved portion which is curved from the bottom portion 10C of the casing 10 in the vicinity of the surface 21B of the contact portion 21 toward the +X direction and the +Z direction as shown in Fig. 6 . And a flat portion disposed on the +Z direction side of the curved portion along the XY plane, but is not limited thereto.

For example, as shown in Fig. 7(A), it is possible to use a shape having a contact with the contact force of Fig. 6 to cause the concave portion 40 to be reversed in the Z direction, that is, from the casing 10 located near the face 21B of the contact portion 21. The flat portion extending along the XY plane of the bottom portion 10C and the contact portion of the curved portion disposed on the +Z direction side of the flat portion have a concave portion 40A.

Further, a contact having a cross-sectional shape of a right-angled triangle as shown in FIG. 7(B) may be used to generate the concave portion 40B, or As shown in Fig. 7(C), the contact forming force of the cross-sectional shape of the cross-sectional shape in which the concave portion 40B is reversed in the Z direction with the contact force of the seventh (B) drawing is used to generate the concave portion 40C.

Further, it is also possible to form a contact having a rectangular sectional shape and then a force generating recess.

It is also possible to form a plurality of contacts for one contact 20 and then force to create a recess. For example, as shown in Fig. 7(D), two of the curved portion and the flat portion may be overlapped in the direction perpendicular to the surface 21B of the contact portion 21, similarly to the contact adhesion force generating concave portion 40 of Fig. 6, respectively. The contact force creates a recess 40D. At this time, the portion 10E of the casing 10 that is in contact with the contact-side fixing portion 23 is generated toward the contact-side fixing portion 23 by the water pressure P for the two contact-contact force generating inner wall surfaces of the recess 40D. Stress can be used to combine the forces of these stresses.

Further, as shown in Fig. 7(E), in the same manner as the contact adhesion force generating concave portion 40C shown in Fig. 7(C), the two contact adhesive force generating concave portions 40E having the cross-sectional shape of the right triangle are superposed on each other. In the direction perpendicular to the surface 21B of the contact portion 21, and the two contact portions having the same cross-sectional shape as the contact-receiving concave portion 40A shown in FIG. 7(A) may be used to generate a concave portion, or as in the first The contact-receiving force-receiving recessed portion 40B shown in Fig. 7B has two recessed contact portions having the same cross-sectional shape, and the recessed portion is formed in a direction perpendicular to the surface 21B of the contact portion 21.

Further, the contact adhesion force generating concave portions 40A to 40E shown in the seventh (A) to (E) diagrams are only one example, and are not limited to have such sectional shapes. set.

Similarly, three or more contact force generating concave portions may be arranged in a direction perpendicular to the surface 21B of the contact portion 21 with respect to one contact 20 .

Embodiment 3

Fig. 8 is a front elevational view showing the waterproof connector of the third embodiment. In the waterproof connector of the first embodiment, the housing 11 having one contact and the force generating recess 41 formed in the bottom portion 11C is used instead of the plurality of contacts disposed on the bottom portion 10C to generate the recess 40. Housing 10. The other configuration is the same as that of the waterproof connector of the first embodiment.

The contact forming force generating concave portion 41 formed at the bottom portion 11C of the casing 11 corresponds to the plurality of contacts 20, and extends in the Y direction toward the arrangement direction of the plurality of contacts 20, and the plurality of contacts 20 are respectively separated The +Z direction side is close.

Even if the above contact is used to generate the concave portion 41, when the electronic device to which the waterproof connector is attached is submerged and the opposite side connector accommodating portion S of the waterproof connector is immersed in water, the water is immersed in the connector with the opposite side. The contact portion of the portion S is connected to the force generating recess 41 so that the water pressure P acts on the inner wall surface of the contact and the force generating recess 41, and the portion of the casing 11 that is in contact with the contact side fixing portion 23 of the respective contact 20 The portion generates an adhesive force toward the contact side fixing portion 23. Therefore, similarly to the waterproof connector of the first embodiment, the peeling of the casing 11 from the contact-side fixing portion 23 of each of the contacts 20 can be prevented, and the waterproof property can be improved.

In the third embodiment, since one contact is formed corresponding to the plurality of contacts 20 and the force generating recess 41 is formed, the manufacture of the waterproof connector is simplified.

Further, the cross-sectional shape of the XZ plane of the contact-receiving force generating recess 41 is not particularly limited, and for example, the shapes shown in FIGS. 6 and 7(A) to (E) can be used.

Embodiment 4

Figures 9 and 10 show the configuration of the waterproof connector according to the fourth embodiment. In the waterproof connector of the first embodiment, the waterproof connector is replaced with a casing 34 instead of the casing 30, and the casing 12 is used instead of the casing 10.

The outer casing 34 has a hollow fitting portion 35 disposed in the opposite side connector accommodating portion S, and a pair of outer casing side substrate connecting portions 36 exposed outside the casing 12, similarly to the outer casing 30 used in the first embodiment; And a case-side fixing portion 37 that is inserted between the fitting portion 35 and the pair of case-side substrate connecting portions 36 and embedded in the casing 12. The fitting portion 35 and the outer casing side substrate connecting portion 36 are the same as the fitting portion 31 and the outer casing side substrate connecting portion 32 of the outer casing 30 used in the first embodiment.

Similarly to the outer casing side fixing portion 33 of the outer casing 30 used in the first embodiment, the outer casing side fixing portion 37 is formed in the casing 12 from the +X direction end portion of the hollow fitting portion 35 on the -Z direction side. The +X direction extends and is connected to the pair of outer casing side substrate connecting portions 36 through the casing 12, and further has +X from the +Z direction side portion of the fitting portion 35. The directional end portion extends within the housing 12 toward the +X direction.

On the other hand, the casing 12 is a bottom portion 12C in the direction of the fitting axis C, at the root of the joint portion 21 of the plurality of contacts 20 and from the vicinity of the face 21B toward the +Z direction to the extending portion 37A of the outer casing 34. The vicinity of the vicinity has a shape recessed along the fitting axis C of the rear surface 12B of the casing 12 and has a contact force generating recess 42 that communicates with the opposing side connector accommodating portion S. As shown in Fig. 11, the end portion of the force generating concave portion 42 in the -Z direction extends in the Y direction toward the direction in which the plurality of contacts 20 are arranged, and is adjacent to the respective +Z direction sides of the plurality of contacts 20. Then, the end portion of the force generating concave portion 42 in the +Z direction is close to the -Z direction side of the extending portion 37A of the outer casing 34.

The casing 12 has the same configuration as the casing 10 used in the first embodiment except for the force generating recess 42.

When the water is immersed in the opposite side connector accommodating portion S of the electronic device immersed in the waterproof connector, the water is also immersed in the urging force generating recess 42 so that the water pressure P acts on the urging force generating recess 42. Here, the casing 12 is supported by the substrate or the casing of the electronic device and the extending portion 37A of the casing 34 is supported by the casing 12 such that the end portion of the adhesion generating portion 42 in the -Z direction is located in the vicinity of the plurality of contacts 20. The +Z direction end is located in the vicinity of the extension 37A of the outer casing 34. Therefore, the water pressure P acting on the inner wall surface of the force generating concave portion 42 is generated in the portion of the casing 12 that is in contact with the contact side fixing portion 23 of the plurality of contacts 20 toward the contact side fixing portion 23. At the same time as the force, the portion of the housing 12 that is in contact with the extension 37A of the outer casing 34 is created to follow the extension 37A. force.

That is, the force generating concave portion 42 is a contact that has both the contact force of the housing 12 toward the contact side fixing portion 23 of the contact 20, and the force generating concave portion and the adhesive force for generating the extending portion 37A toward the outer casing 34. The outer casing then forces to create a recess.

As a result, the peeling of the casing 12 from the contact-side fixing portion 23 of each of the contacts 20 and the peeling of the casing 12 from the extending portion 37A of the outer casing 34 are prevented, and the waterproof property can be improved.

In the fourth embodiment, the one end force generating concave portion 42 corresponding to the plurality of contacts 20 and the outer casing 34 is disposed on the bottom portion 12C of the casing 12, but a plural number divided in the arrangement direction of the negative number of the contacts 20 may be disposed. The subsequent force creates a recess 42.

When the outer peripheral surface of the outer casing side fixing portion 37 is formed by a plurality of grooves or projections that are parallel to each other, and the outer side waterproofing portion for water infiltration along the boundary surface between the outer casing side fixing portion 37 and the casing 12 is formed, The combination of the force generating the recess 42 causes the peeling prevention effect of the casing 12 from the extending portion 37A of the outer casing 34 to enhance the waterproof effect on the outer casing 34.

Embodiment 5

Fig. 12 is a front elevational view showing the waterproof connector of the fifth embodiment. In the waterproof connector of the fourth embodiment, the waterproofing connector of the fourth embodiment is formed by using a housing 13 having a contact at the bottom portion 13C and a recessed portion 41 and a housing and a force generating recess 43 independent of each other instead of being disposed on the bottom surface 12C. The force then creates the housing 12 of the recess 42. The other composition is The same as the waterproof connector of the fourth embodiment.

The contact adhesion force generating concave portion 41 at the bottom portion 13C of the casing 13 is formed in the Y direction and each of the plurality of contacts 20 in the same manner as the contact adhesion force generating concave portion 41 used in the waterproof connector of the third embodiment. When the +Z direction side is close, when the water is immersed in the opposite side connector accommodating portion S of the waterproof connector, the water pressure P acting on the inner wall surface of the recess 41 by the contact force is applied to the contact side with each contact 20 The portion of the casing 13 that the fixing portion 23 contacts generates an adhesion force toward the contact side fixing portion 23.

On the other hand, the outer casing rear force generating concave portion 43 is close to the -Z direction side of the extending portion 37A of the outer casing 34, and when the water is immersed in the opposite side connector accommodating portion S of the waterproof connector, the concave portion is generated by the contact force acting on the contact. The water pressure P of the inner wall surface of the flange 43 generates an adhesive force toward the extending portion 37A at a portion of the casing 13 that is in contact with the extending portion 37A of the outer casing 34.

As described above, even if the contact-receiving force generating recess 41 and the outer casing rear-force generating recess 43 are formed independently of each other, the housing 13 can be prevented from being fixed from the contact side of each contact 20 as in the waterproof connector of the fourth embodiment. The peeling of the portion 23 and the peeling of the casing 13 from the extending portion 37A of the outer casing 34 can improve the water repellency.

Further, the cross-sectional shape of the outer casing and the force generating concave portion 43 in the XZ plane is not particularly limited. For example, the contact force shown in Fig. 6 and the seventh (A) to (E) is used to generate the concave portion 40, 40A to 40E. The same cross-sectional shape.

In the above-described first to fifth embodiments, although five contacts 20 are arranged in the Y direction, the number of contacts 20 is not limited to five, and the present invention can be widely used. A connector having more than one contact 20 is used universally.

Further, the present invention can also be applied to a connector that does not have the outer casing 30 or 34 when electromagnetic wave shielding is not required.
